Figure 2 is a sectional perspective view Vof i a part thereof.-

l Y Figure 3 is a sectional view on the line 38 of Figure lj e v u In the ,embodimentV disclosed, abacking sheet Ll is employ-edV that is preferably multij ply. It comprises a rear body ply 5 of cardboard or other heavy material, a facing sheet 6, preferably of relatively lightpaper, and an intermediate Waterproof ply 7 that serves to secure the facing sheet (Sand rear ply V,5together, while preventing the passage of moisture from the wet plaster to said ply 5. In this respect the structure is similar tothat disclosed in our co-pending applicati'om'Serial No. 339,085, filed on Feb. l1, 1929.

VThe backing sheet 4 considered as an eno tity is provided with depressions VJforming pockets that are open on the side of the facing sheet 6. These depressions or pockets are elongated and are arranged in rows, both A longitudinally and transversely ofthe sheet.

extend in one direction andthe other pockets 9 extend in rows at right angles to the rows 8. VThe pockets of each rowY are located end l to end and said ends terminate-short of one 40 another, but the pockets of the longitudinal and transverse rows intersect: It will also be noted that the pockets of one row are located in staggered relation to the pockets of the adjacent rows, both longitudinally and trans- `formed by depressions, they thus provide ribs extending both transversely and vlongitudinally of the sheet and so related that they stiifen the sheet against bending and breaking down. Looked at from another standa're `laidV along thelface sheet 6 and extend longitudinally over the respective rows of `the poclrets,are spaced from the bottoms of That is to say, one set-of rows of pockets S Y fribsthat help to make 'ith-e entire wall structure rigidfboth y've:rsely.

versely of the sheet and vas these pockets are f sets arranged in rows, those of one row being.'

staggered with relation to the adjacent rows..

Longitudinal and transverse lath rods l0.1`

pockets 8 and 9j lhey thus intersect .at-the intersectionofthe pockets and they also -interseotV on theflat portions of the sheet bef tweenthe adjacent ends of the pockets. At om Vtheselatter points of intersectionystaples 11 pass: over .the intersecting portions and `through the sheet where they are suitably clinchedy and thus hold the rodsV in place.

As a result oi: this structure iit will be evident that the metal vlath fabric Vlies along the `faceof the"baclring'sheet, preferably with the under rods against the sarneandzthat these rods extending; in intersecting relation over said pockets. Gbviously 'therefore `when plaster is appliedas indicated in Figure '2, av

relatively thin coat only 'is necessary and yet; this plaster entering the pockets 'will sur-- round the portions 'of kthe rods extending thereacross and will'be properly keyed. The facing sheet constitutes a bonding medium between'the"plasterV and theba'clring sheet and the rear or supporting ply 5 of sa-idi` backing `sheet will not be moistened because of the waterproof lining@ in advance of the saine. .A Said backing or supporting ply `5 is 'thus' not Vweakened during'the application and setting of the plaster and the wall after .1 the plaster hardens becomes -a iirrn and rigid structure. Moreover when the plaster has set, the portionsVv thereof that Ahave lentered the' pockets-form shortcrossed reinforcing.
